ARTIFICIAL FUEL,

EPECIFICATION forming'part of Letters Patent No. 301,525, dated July 8,1884.

Application filed August 3, 1883. (No specimens.)

In all whom 2125 may concern.-

Be it known that I, AUeUsrn ROMEAU, a citizen of the United States,residing at Cleveland, county of (luyahoga, and State of Ohio, haveinvented a certain new and useful Improvement in Artificial Fuel; and Ido hereby declare the following to be a description of the same, and ofthe manner of making and using the invention, in such full, clear,concise, and exact terms as to enable any person skilled in the art towhichit appertains to make and use the same.

My artificial fuel is made from the waste or refuse of coal, mixed withanimal-blood and quiclrlirne. The coal may be either hard or soft, thefuel being very easily made from anthracite coal. The material used maybe the ordinary refuse or waste, such as the slack, This coal waste isunited with the quicklime and blood'in parts and proportionssubstantially as follows: To a ton of coal refuse, twenty gallons (moreor less) of animalblood is used, and twenty five pounds (more or less)of pulverized quicklime. The blood and the quicklim'e may be first mixedtogether, then added to the coal refuse, and the entire mass be wellmixed together. The blood and the quicklime form a pasty compound,whichserves as a binder to hold the particles of the coal refusetogether. The mixture is then molded into form for fuel.

The several ingredients of the mixture are very cheap, and hence theresultant fuel is of slight initial cost.

The form of the fuel may vary with the use for which it is intended.Thus, for domestic use, the block may be smaller than when intended forthe use of manufactories.

The machinery required to make the fuel is very simple, as but slightpressure is required in molding.

The fuel is ready for use within a day after its manufacture, astheblocks dry quickly after being taken from their molds.

The fuel burns like ordinary coal, preserves 45 If it is desired thatthe fuel shall be quite compact so as to burn a long while, the coalrefuse may be ground to a corresponding dcgree of fineness previous tothe addition of the quicklime and blood. The blood, when dry, ignitesreadily, thus adding to the combustibility of the coal.

The fuel is clean to handle, and is not appreciably affected by water.

If it is desired to make the fuel. cheaper than it can be produced byusing pure blood in the proportions previously set forth, alessquantity. of pure blood may be diluted with water sufficient to makethe described proportion.

Heretofore certain fertilizing compounds have used one or more of theelements employed in my mixture. For instance, one uses blood and slakedlime; another uses blood, coal, and a phosphate. The difference in unityof composition between such fertilizers and my fuel is apparent.
